Sports Illustrated Swimsuit Models Take Over David Letterman's Top Ten (Video)

With the 2013 Sports Illustrated Swimsuit Issue about to hit newsstands soon, the ladies within the pages made an appearance at the Late Show with David Letterman. While there, the models did Letterman's Top Ten on "Questions on the Application to Become a Sports Illustrated Swimsuit Model." Honestly, each girl did their thing but Katherine Webb's part may have been the best of them all.
